- three vehicles 10 a to 10 c are traveling on the circulation route.
- the vehicle 10 returns to the base and switches with another vehicle 10 on standby.
- switches indicates that the vehicle 10 returns to the base from the circulation route and that the other vehicle 10 on standby is introduced into the circulation route from the base.

- the controller 23 includes at least one processor, at least one programmable circuit, at least one dedicated circuit, or a combination of these.
- the controller 23 controls the operations of the entire server 20 . Details of the operations of the server 20 controlled by the controller 23 will be described later.
- Step S 100 The controller 23 of the server 20 stores the operation schedule of the plurality of vehicles 10 in the memory 22 .
- the operation schedule may, for example, be generated automatically by the controller 23 , inputted by an operator, or acquired from an external apparatus via the communication interface 21 and the network 30 .
- Step S 101 The controller 23 starts monitoring the status of the plurality of vehicles 10 .
- the controller 23 is communicably connected to each vehicle 10 via the communication interface 21 and the network 30 .
- the controller 23 notifies the plurality of vehicles 10 of the operation schedule of step S 100 .
- Each vehicle 10 operates in accordance with the operation schedule notified by the server 20 .

- Step S 102 The controller 23 judges whether the vehicle 10 traveling on the circulation route has experienced failure before completing the specified number of laps n. When it is judged that the vehicle 10 has experienced failure (step S 102 : Yes), the process advances to step S 103 . Conversely, when it is judged that the vehicle 10 has not experienced failure (step S 102 : No), the process repeats step S 102 .
- Step S 103 When it is judged in step S 102 that the vehicle 10 has experienced failure (step S 102 : Yes), the controller 23 revises the operation schedule stored in step S 100 .
- Step S 104 The controller 23 newly assigns a portion of the operation schedule that was assigned to the vehicle 10 that experienced failure to another vehicle 10 .
- the controller 23 notifies the plurality of vehicles 10 of the operation schedule after the revision in steps S 103 and S 104 .
- the process subsequently advances to step S 102 .
- the target for assignment of the operation schedule may also be a vehicle 10 other than the vehicles 10 a to 10 g.
- an embodiment in which the configuration and operations of the server 20 in the above embodiment are distributed to a plurality of information processing apparatuses capable of communicating with each other can also be implemented.
- an embodiment in which some or all of the components of the server 20 are provided in the vehicle 10 can also be implemented.
- an upper limit may be set on the number of substitute vehicles 10 that can be introduced into the circulation route during a certain time period going back from the current time (such as the time period from the current time to 3t ago in the case in which the time required for the vehicle 10 to travel one lap of the circulation route is 3t). If a plurality of vehicles 10 on the circulation route experienced failure in a relatively short period of time and failure switching were implemented for each of the vehicles 10 , the number of vehicles 10 on standby at the base might become less than planned or reach zero. In such a case, inconveniences such as an inability to implement the scheduled normal switching may occur.
- the above-described configuration for setting an upper limit on the number of substitute vehicles 10 that can be introduced into the circulation route reduces the probability of such inconveniences occurring.
- the time distance between a vehicle 10 traveling on the circulation route and another vehicle 10 traveling on the circulation route may become shorter than scheduled if deviation from the operation schedule (such as delay time) increases.
- the time distance between the vehicles 10 traveling on the circulation route is scheduled to be t. If a vehicle 10 is delayed relative to the operation schedule, however, the time distance may be reduced by the amount of the delay.
- the controller 23 may, for example, judge whether any of the vehicles 10 traveling on the circulation route has a time distance from the base of less than a reference value (such as t). The controller 23 may then withhold introduction of the substitute vehicle 10 until there is no longer a vehicle 10 with a time distance from the base of less than the reference value.
- a general purpose computer functions as the server 20 according to the above embodiment
- a program in which processes for realizing the functions of the server 20 according to the above embodiment are written may be stored in a memory of a general purpose computer, and the program may be read and executed by a processor.
- the present disclosure can also be implemented as a program executable by a processor, or a non-transitory computer readable medium storing the program.
